Are you suggesting that the third dose doesn’t provide lasting protection against the Delta variant? What data led you to that conclusion? And what do you propose should be the focus?
I’m suggesting this big increase in antibodies will be shortlived, just like what is likely happening after the second booster shot.
That increase in antibodies will obviously help protect against Delta stronger in the short term. What do you call “lasting protection”? Most medical people commenting I’ve seen think two shots gives strong lasting protection against Delta causing severe illness.
But the real issue is that in the US, Delta is surging amongst the unvaccinated, not the people with two shots. So I can’t see it being a huge public health benefit to try and get the fully vaccinated people a third shot.
I’m looking for the data on which you based your personal conclusions. If you’ve got some specific data you’ll share, great.
So far it seems to be a lay-person’s opinion, based on a very superficial knowledge of the science behind immunology. I read this thread to get breaking news, not opinions from non-experts.
There is no data on long term protection from a third dose. My personal opinion is there’s no reason to assume a third dose gives stronger long term immunity. Antibody levels fade after exposure, this is just a fact of the immune system. What exactly are you expecting me to back up with data?
I guess I need you to answer, “what do you mean by lasting protection?” if you want a better answer out of me. And it should probably be in another thread.
Moderating:
Yes, it should.
Same here. For that reason, I don’t feel the need to start a new thread.
I’ve read this article, and I get the feeling that the headline exaggerates a bit from the message the CDC intended, but I’m not 100% sure.
Personal anecdote: a fully vaxxed friend (Pfizer) just tested positive, and his only indoor exposure was eating at a restaurant in a highly-vaccinated city. So far it’s like a mild cold so the vaccine is doing its most important job, but it still shows the risks of going mask-free even if you and most nearby people are vaccinated.
This is good— surprising, but good.

The 60-second spot will be paid for by McConnell’s reelection campaign and will draw on his experience surviving polio as a child, according to a source familiar with the ad. The senator’s plans were first reported by Reuters.“Every American should take advantage of this miracle, and get vaccinated,” McConnell says in the ad, according to a script obtained by HuffPost. “It’s the only way we’re going to defeat COVID. This is not complicated. 97% of people hospitalized for COVID are not vaccinated.”
“If you haven’t been vaccinated, do the right thing for you ― for your family ― and get vaccinated right now,” the senator continues.

Dr. Fauci was on “All In with Chris Hayes” last night, and talked a little about this. Apparently, nasopharyngeal viral loads in breakthrough infections are similar to those who haven’t been vaccinated; however, upper respiratory viral loads are much lower in the breakthrough infections. Thus, the breakthrough infections are less severe and not as life threatening - to the point that the breakthrough-infected may not know they’re quite contagious.
I need to poke around for more information about this.
196,707,763 total cases
4,203,682 dead
178,113,916 recovered
In the US:
35,487,490 total cases
628,098 dead
29,603,958 recovered
Yesterday’s numbers for comparison:
In early June 2021, the number of new cases per day worldwide dropped below 400,000 and stayed there for about 30 days. Then the numbers began to creep upward and now that pace is accelerating: two weeks ago the numbers crept upwards of 500,000 per day, although there was some fluctuation.
Two days ago there were 466,000 new cases worldwide.
Yesterday there were 595,000 new cases.
Today, there were 649,000 new cases.
The US numbers show a similar increase: two days ago there were 52,050 new cases in the US. Yesterday there were 77,825 new cases and today there were 84,534 new cases in the US.

Wear a mask. Wash your hands. Keep your distance. Stay safe.
Sure, but this evidence is talking about 7 people.
If you look at the study, they took data on 1497 vaccinated healthcare workers, and 39 of those people later tested positive. And 19% of them had symptoms 6 weeks later. 19% of 39 people is 7.41 people.
Dr. Michele Longo, an assistant professor of neurology at Tulane University in New Orleans who works with long-haul patients, said she has not seen such patients following a breakthrough infection. Neither has Dr. Maureen Lyons, medical director of the Care and Recovery from Covid-19 Clinic at Washington University in St. Louis.
Dr. Ziyad Al-Aly, a clinical epidemiologist, also at Washington University, is studying the effects of Covid-19 vaccination on the risk of long Covid-19. His research, which is not yet finished, looks at information on more than 5 million veterans within a Department of Veterans Affairs database, including 200,000 who were diagnosed with Covid-19.
“Of the people who get vaccinated and end up with a breakthrough infection, their risk of coming back to the clinic with some long Covid manifestation is very, very small,” Al-Aly said.
COVID news ping pong!
Possibly behind a paywall. Some of the points from the article:
-
“These are the Americans who are being vaccinated at this moment in the pandemic: the reluctant, the anxious, the procrastinating.”
-
“… they occupy a middle ground: For months, they have been unwilling to receive a coronavirus vaccine, until something or someone — a persistent family member, a work requirement, a growing sense that the shot was safe — convinced them otherwise.”
-
“Their answers [why they are getting the vaccine] suggest that the mandates or greater restrictions on the unvaccinated that are increasingly a matter of debate by employers and government officials could make a significant difference.”
-
‘“Some people come in and they’re still hesitant,” she said. “We have to fight for every one of them.”’
There are people now getting vaccinated solely so that they can attend Lollapalooza in Chicago, which starts today.
Here’s what I wonder about stories like this: do they actually tell us anything we can’t already guess? I mean, it’s great for confirmation, so we can add to our knowledge, but it never seemed to me like, in this case, it was absolutely impossible for breakthrough cases to go long or what have you.
Pfizer and Moderna use very similar technology. So far, at least, they have similar levels of effectiveness.
The army has been called out to enforce the lockdown in Sydney. Our case numbers are still peanuts by world standards, but growing every day (over 200/day).
